Quality Assurance

100% Stability, 100% Reliability — Every Product, Three Rounds of Inspection

Quality Assurance

Quality Inspection

Every product goes through three rounds of strict quality inspection.

Dimensional, hardness and density checks at every production stage.

High-resolution optical inspection ensures every insert meets specs.

Quality Assurance

ISO9001 certified, verified by SGS video inspection, and recognized as an Alibaba Verified Supplier.

Owner of the proprietary "HARDVIK" brand, backed by multiple invention and utility model patents.

Fully licensed for independent import/export operations, with support for multi-currency local payments worldwide.

Manufacturing

From raw powder to finished product — 7 steps of precision manufacturing.

Precise formulation of tungsten carbide powder, cobalt binder, and grain growth inhibitors according to grade requirements.

CNC automatic pressing machines form the powder into insert blanks with consistent density and dimensional accuracy.

Vacuum sintering at 1400-1500°C followed by HIP (Hot Isostatic Pressing) for maximum density and strength.

Precision grinding on CNC machines to achieve tight dimensional tolerances and superior surface finish.

Precision edge sharpening to create the cutting geometry required for optimal machining performance.

Edge passivation treatment to improve tool life and prevent chipping during high-speed cutting operations.

PVD/CVD coating application in various colors (bronze, gold, black, nano blue, etc.) for enhanced wear resistance.

Experience the difference of 100% stability and 100% reliability.
